Generally, I'd use strings to set running headers. Like this:

  @page { @top-center { content: string(header) }}
  h1 { string-set: header }

In which case there is no need to duplicate content. 

If the running header has structure (e.g., if there's an <em>
element inside the header), one has two option:

 - duplicate the content and use the element() function. 


I don't think this is tag abuse, but being able to clone the document
may still appeal to some. A solution for this is sketched here, in the
copy() function:


This is still early work.

What would the code look like?
